ctrlro, I had the same problem as you in the UK.
These are the steps I used to upgrade to the official B934
1) I used another SD; card 8Gig
2) Format SD card using CWM
3) CWM factory reset
4) Middle package to downgrade to stock B885 - using software upgrade method from SD card
5) Over The Air upgrade to B892
6) Middle package to upgrade to stock B934 - using software upgrade method from SD card
Been using 2 days now and no reboots so far, it is HSPDA: 9
